Inventor: TASHIRO YOSHIYUKI
IPC: B21D51/16
Filed: 1993-02-02
Abstract: PURPOSE:To provide a flexible tube completely eliminating straight tube parts and without impairing flexibility by forming a swelling part being at end parts with a larger diameter than at other swelling parts in flexible tubes provided with many annular swelled parts, successively. CONSTITUTION:On the circumferential surface of a flexible tube main body 1 made of a thin stainless steel, many annular swelling parts 2 are provided successively by a tube expansion method. A flange 3 provided at both ends of the tube main body 1 is formed with a larger diameter than the swelling part 2. The flange 3 is formed, after the valley part between the wo swelling parts being at the end side of the swelling parts 2 is pressed in the outward direction A from inside to form circular arcuate swellig parts 5, by crashing the swelling parts 5 for the adhesion of the inside wall in the axial direction B by press working. Consequently, since no straight tube part exists, the flexibility is not impaired, and the damping property is improved; since the contact area for packing is secured, a satisfactory sealing property is obtained.

Title: Method and device for heat-sealing thermoplastic pipe
Inventor: TARUMAN ARUFURETSUDO
IPC: B29C65/22
Filed: 1984-02-02
Abstract: A system for heat-sealing thermoplastic conduits involves a thermoplastic sleeve surrounding an electrically conductive heating wire arranged in a coil. A bridging conductor is located adjacent the heating element, but is separated from it by an insulation layer of predetermined thickness. When the sleeve is heated by supplying electric power to the heating element, the entire heating element generates heat during a first phase in which fusion pressure is applied between the sleeve and pipes being connected. The bridging connector is forced into contact with selected coils of the heating element to initiate a second phase. In the second phase, the heat produced in the area of the selected coils is automatically reduced by short circuiting such coils.
